Model Binder Providers in Asp.net Core
ASP.NET Core that you want to use your custom model binder for a specific type, you create a model binder provider. This provider implements the IModelBinderProvider interface.
 
Code
// (This code is not provided in your original request, but it’s a common way to register a custom model binder)
 
public class PersonBinderProvider : IModelBinderProvider
{
    public IModelBinder? GetBinder(ModelBinderProviderContext context)
    {
        if (context.Metadata.ModelType == typeof(Person))
        {
            return new BinderTypeModelBinder(typeof(PersonModelBinder));
        }
        return null;
    }
}
This provider checks if the model type is Person, and if so, it returns an instance of your PersonModelBinder.
 
 
Registration and Usage
// Program.cs (or Startup.cs)
builder.Services.AddControllers(options => {
    options.ModelBinderProviders.Insert(0, new PersonBinderProvider());
});
By inserting your PersonBinderProvider at index 0, you ensure it takes precedence over the default model binders.
